CHAIN CLAMP.

Application filed August 4, 1923.

To all 1072mm 2'2- may concern.

Be it known that I. OLE Vrornn, a citizen oi"? the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improve cuts in Chain Clamps, of which the tolhf. if is a specification.

This invention relates to chain clamps and more particularly to an improved device for engaging the ends or a chain and drawing it taut so that it will be held under a tension while it is being used.

The primary object of the invention is to provide a device for stretching and holding a chain in position around the molds for forming concrete pillars or the like in the building art.

The invention has for another object the provision of a simple arrangement of levers adapted to be connected to a chain and operated to pull the same tightly under a tension.

Other objects of the invention will appear upon consideration of the following detailed description and accompanying drawing in which:

Figure 1 is a plan View of a concrete mold showing my invention applied thereto,

Figure 2 is a side view of a portion of the invention showing it in operative position, and

Figure 3 is an edge elevation of the same.

Referring to the drawing by numerals, the chain 1 is provided at one end with a clevis 2 which is pivotally connected to a lock hook 3 substantially semi-circular in configuration and this look hook is connected to the curved end 4 of a stretcher lever 5 and the pivot member 7 which connects the hook 3 with the portion 4: is offset with respect to the longitudinal center line of the clevis as shown so that when the stretching lever is in operative position the loop 8 of the swivel chain 9 will be engaged by both the curved end 4 of the lever and the curved end of the lock hook 3 as shown. The swivel 9 is connected to an adjustable hook 10 which is provided with a series of hook notches 11 to which the end 12 of the chain may be connected. When the stretching lever is in operative position its end 13 is engaged by a latch 14 which is in the form of a loop carried by one of the links of the chain and is adapted to pass over the end of the lever and register with a notch Serial No. 655,592.

formed therein. This notched end of the loop 14 is normally held in position by a removable clip 15 attached to the stretching lever 5.

When the apparatus is in use, the chain will be placed around the implement which is to be held together and the adjustable hooks 1O engage with one end of the chain. The stretching lever will then be passed through the loop 8 of the swivel and the lever will be drawn down into parallel re lation with the opposite end of the chain to which the clevis 2 is attached. This action of the lever causes the hooked or curved portion a of the lever to draw the swivel toward the clevis 2 thus tightening the chain and when the lever has been pushed downwardly to its lowermost position, it may be held thereby through the medium of the latch 13 and clip 15.

Minor changes may be made in the details of construction without departing from the spirit of the invention or the scope of the claims hereunto appended.

What I claim, is:

1. A chain clamp of the character described comprising a chain having a swivel clevis carried at one end thereof, a semicircular lock hook attached to the clevis, an elongated lever having a curved end pivotally attached to the said lock hook, an adjustable hook, a swivel connected to the adjustable hook and formed with a loop to engage the curved ends of said lever and lock hook, the said adjustable hook being adapted to receive the opposite end of the chain, said elongated lever having a notch therein at the end opposite to that where the same is curved, a second loop carried by said chain and adapted to engage over the end of said lever and in said notch, and a member pivoted to said lever for engaging over said second mentioned loop.

2. A chain clamp comprising, in combination with a chain, a clevis carried by one end of the chain, a loop carried at the opposite end of said chain, a lock hook substantially semi-circular in formation and having one end attached to the said clevis. a stretcher lever equipped with a curved end pivotally attached adjacent the other end of the said lock hook, the said pivot being off-centered with respect to the longitudinal center line of the said clevis with said curved ends of said adjustable lever swivel adapted to be releasahly connected and lock hook both engaging said loop at In testimony whereof, I have affixed my the opposite end of said When When in an signature in the presence of two witnesses. 10 operative position, means to maintain the stretcher lever in operative position, and a OLE VICTEL.

to the hook and curved end of the lever and T/Vltnessesz adjustably connected to the opposite end of I JAMES CUSHNIE,

the said chain. c J ACK STACK.
